My command invoking pscoast with an azimuthal projectiontrying to plot a hemisphere centred on a point in Asiafails in v. 5.1.1 but not in v. 4.5.12.Here is a test command that I wrote to illustrate the problem.pscoast -Ja30.0/30.0/90.0/1.4/100.0 -Rg -B30/30WESN -A5000 -Dc -G40/255/128 -S100/200/255 -W > jjpscoast.psgives this:pscoast (gmt_radial_boundary_arc): Error: Could not reallocate memory [68719476736.00 Gb, 9223372036854775806 items of 8 bytes]If I eliminate the -G and -S options then it runs to completion but all the co-ordinates in the postscript file are zero. In V. 4.5.12 it worked OK. Test script below also contains the error messages. I appreciate that the coastlines at the edge of this hemispherical projection are going to be very distorted.

Thanks. I still can't get it to work with -Ja - I clearly don't understand the documentation ("man gmt") - but it works with JA30.0/30.0/90.0/14.0 so I will go with that. I thought that what I had put was correct, i.e. that the final 1.4/100 represented "radius/lat" i.e. radius of plot = 1.4 cm out to oblique latitude 100 deg.

We bave decided to stick with the long-time practice of specifying radius/lat instead of scale, in which radius is the projected distance on the map from the projection center to a particular oblique latitude around that center. Hence, an oblique latitude is given in the -90 to +90 range, We have added a check that if anything > 90 is given (a colatitude) we now give an error. This should prevent cases like yours from crashing and give a meaningful error message. In r13470.
